Abstract
The properties of the motion occuring in the machine tool slideway are closely connected with the characteristics both in static and kinetic friction. In a previous paper, the static friction in the stick period was investigated. It has been shown in this paper that the characteristics of kinetic friction in the slip period can be examined collectively using the mean kinetic frictional coefficient μm in this period, and that the main factors which affect μm are the static frictional coefficient at the beginning of the slip motion and the time of the slip period. As a result, an expression for μm is proposed. Then, basing on the expressions for static and kinetic friction, the boundary conditions for occurrence of the motion are clarified, and the relation between properties of the motion and frictional characteristics is examined quantitatively.
